Problems solved by technology
In the specific production process, the heat exchange is optimized through performance matching, and the split flow is determined. According to the assembly and system reliability, a certain flow path of the evaporator is selected to weld the temperature sensor, and the temperature value is read to realize the air conditioning system. However, due to the shape of the air conditioner itself, the design of the evaporator is irregular, and the air supply is uneven, which will actually cause the actual heat transfer of each flow path of the evaporator to be different, that is, every There may be differences in the temperature of each branch. When the deviation of each branch becomes larger, it may cause inaccurate temperature reading and unreasonable control, which will lead to condensation and water blowing from the internal unit, reducing user experience

The present invention provides an air-conditioning system control method, device, storage medium and air conditioner, wherein the air-conditioning system control method includes: acquiring n real-time temperatures T respectively detected by n temperature-sensing components i And the preset tube temperature T under the corresponding working conditions x , i=1, 2,..., n; get n T i respectively with T x The maximum value of the difference is the first maximum difference △T imaxa , and n T i The maximum value of the difference between any two of them is the second maximum difference △T imaxb , where △T imaxa =∣T i -T x ∣, △T imaxb =∣T i -T m ∣, m=1, 2,..., n and m≠i; when △T imaxa In the first temperature difference interval Q1, and ΔT imaxb ≤Tyb1, control the air conditioning system to operate based on the smallest temperature value among the n real-time temperatures Ti. According to the present invention, by accurately detecting the real-time tube temperature of multiple flow paths of the internal unit evaporator and then judging the risk of condensation on the internal unit evaporator, effectively preventing the occurrence of condensation and water in the air outlet of the internal unit, and improving the user's use experience.
Description
technical field [0001] The invention belongs to the technical field of air conditioning, and in particular relates to a control method, device, storage medium and air conditioner for an air conditioning system. Background technique [0002] At present, the internal unit evaporator of the household split wall-mounted machine has only one temperature-sensing package, which is located on a certain branch of the flow path of the internal unit evaporator. Load protection, fluorine deficiency protection, etc. In the specific production process, the heat exchange is optimized through performance matching, and the split flow is determined. According to the assembly and system reliability, a certain flow path of the evaporator is selected to weld the temperature sensor, and the temperature value is read to realize the air conditioning system. However, due to the shape of the air conditioner itself, the design of the evaporator is irregular, and the air supply is uneven, which will a...
